Dear Sir,
Hope you are doing well !!
Ideally,Form 26QB is to be filled in by each buyer for unique buyer-seller combination for respective share. E.g. in case of one buyer and two sellers, two forms have to be filled in and for two buyers and two seller, four forms have to be filled in for respective property shares.
However, in your case, entire payment has been made by you then you don't require to file 26qb for your wife's name as you will be treated as legal owner of property as per income tax law.
You need to file two forms for the same-one buyer and two sellers, two forms have to be filled in.
No, there is no other form for TDS deduction.
We may assist you in entire compliances and filings.
It is advisable to take a phone consultation for detailed discussion.
